We give a brief review of the Kondo effect and exactly solve thenonequilibrium Kondo problem at the special point in the parameter space of themodel with spin-dependent chemical potentials. Using the obtained solution, wecompute several experimentally observable quantities: charge current, spincurrent and magnetic properties. Applications to the physically important casessuch as the case where the impurity spin is placed in between twoferromagnetically polarized leads are discussed.Comment: 13 pages, 2 figure
